System: NetBSD 9.99.34 NetBSD 9.99.34 (UNPLUGED) #284: Mon Jan 6 12:33:40 CET 2020 evbarm
Architecture: earm
Machine: evbarm

I found a  /dhcpcd.core file on this machine, date around the last time it
rebooted. There is a working dhcpcd process still running and no obvious

This machine has / on NFS and netboots, rc.conf has:

dhcpcd=YES dhcpcd_flags="-6"

gdb is pretty useless:

Core was generated by `dhcpcd'.
Program terminated with signal SIGSEGV, Segmentation fault.
